"We've been ripped off"

When asked about the allegations, Stringer told Apple's counsel, "We've been ripped off… It's a huge leap in imagination to come up with something new. That's what we did."

Samsung's counsel then cross-examined Stringer, discussing the design patents for the iPhone. He then produced as evidence an email Stringer wrote in 2011, asking for a list of competitor tablets that the team could discuss.

It's thought Samsung is trying to allude Apple is as inspired by competitor products - as its Sony-branded iPhone prototype might suggest - as everyone else.

Stringer said the point was to gauge the market, rather than to take inspiration for future designs.

Annoying the judge

Samsung has also succeeded in annoying Judge Lucy Koh by sending rejected evidence to the press that she wouldn't allow in court.

The evidence centres on Samsung's F700 phone, which it was working on in the lead up to the iPhone's launch in 2007. It's been denied because it brought it out too late.

After "begging" her to allow it, Samsung sent out a press release containing the "Sony-style" iPhone prototype, saying it would have "established beyond doubt that Samsung did not copy the iPhone design". Koh was furious, summoning Samsung's lead attorney to find out what part he had to play.
